I live on a semi-rural island in the Pacific Northwest, and have had my range extender for four years. It's performed beautifully, with ridiculously accurate GPS location information - that is, until I recently moved 6.5 miles away from the East to West side of the island. Now my range extender shows my GPS location as 78 miles south of me, near South Seattle. When the range extender is off, and I'm only connected to my in-home wifi, my location is totally accurate. The range extender is located next to a window *and* I use the GPS antenna attached to the inside of the window (just as I did in my previous home). There is no cell signal in the area I live now, so the range extender is my lifeline. Any help would be greatly appreciated.
